They had the best of intentions, but certain public service campaigns ended up making something really bad for you appear awesome. The bad experiences were tempered to keep from frightening children, which only undermined the message. And some downright pushed the bad stuff, like a 1997 physical fitness campaign featuring children gorging themselves on chocolate cake.

Look back at those screencaps! You've never enjoyed anything as much as those children did those chocolate cakes. They make fudge smoothies (which, we're sorry, is a bad idea how? That's the entire business model of Cold Stone Creamery) and even build whole fortresses out of chocolate; that's like the most fun afternoon of anybody's childhood. Have you guys never seen Willy Wonka and the Chocolate Factory? It's like all the best parts of that movie come to life, and without all the child murder.

Other campaigns managed to make drugs and venereal disease look attractive. Read about them all at Cracked. Link
